Memory Tricks
Arteries = flow A-Away from the heart
Veins = think of the V like an arrow shape pointing to the
heart
Capillaries = gets a couple other blood vessels to join
together (biggest word but smallest blood vessel)
Osmosis is diffusion through a membrane
Diffusion is the movement of molecules from an area
of high concentration to an area of low concentration
 Hemoglobin
(ironcontaining protein in red
blood cells) carries oxygen
 Sickle
Cell Anemia
(recessive genetic disease)
results in cresent-shaped
red blood cells that do not
carry oxygen as well

White Blood Cells
Plasma
Platelets
